A teenager was charged with murder Monday night after allegedly shooting someone who he believed abused his relative.

Investigators say that the teen, a group of his friends and family beat, chased and shot Samuel Long, 39, at a home in the 100 block of 20th Avenue East.

“There had been accusations that the victim had abused one of the teenager’s family members,” said Tuscaloosa County Metro Homicide Unit commander Capt. Loyd Baker. “This young man, his friends and other family members went down there to assault him.”

The group went to the home where the teenager lives and the victim sometimes stays, Baker said. Long married the teen’s relative earlier this year, but the couple has been estranged, he said.

The group of teenagers and young adults began to assault Long, who jumped out of a window and tried to run, Baker said.

The 15-year-old fired several shots, hitting Long with at least one bullet. Long collapsed in a nearby yard and was transported to DCH Regional Medical Center where he was later pronounced dead.

The teenager turned himself in to investigators Monday night. He was charged with murder and was being held Tuesday morning at the Tuscaloosa County Juvenile Detention Center.

Several other young men had not been located as of Tuesday morning. They could be charged with assault, Baker said.
